` 1 Claim. (ci. 257-137) This invention relates to devices for circulating heat, particularly of radiators wherein coils -or sections are heated with steam, hot water, or the like, rand in particular, a housing framed over a radiator and a fan for circulating air around theicoils of the radiator whereby the air passes through openingsv in the lower end of the .housing so that heat is distributed over the lower part heated air passing upwardly, filling the upper portion of' the room and whereby the cooler air is forced downwardly, eventually finding its way4 to the radiator by which lit is heated and the cycle of circulation repeated. With this thought in mind, this invention contemplates forced` draft means in combination with a radiator in which the forced draft is supplied to the upper end of the radiator and in which theonly escape `therefor is through openings around the bottom of the radiator. By this means air from the intermediate portion of a room is drawn into a relatively thin area around a radiator, forced downwardly and discharged into the cool portion of the room the radiator.

The object of this invention is, therefore, to provide means for stimulating circulation of air over a radiator whereby cool air is continuously blown over a radiator and, after being heated by the radiator, is discharged in the lower part of a room or enclosure.

A further object of the invention is to provide means for circulating the air of a room or enclosure over a radiator in which air passages around sections or coils of the radiator are comparatively thin so that the air is brought into close proximity of the surface of the radiator and consequently rapidly heated in which the device is of a simple and economical construction.

With these and other objects and advantages in view, the invention embodies a housing for a radiator which, except for an inlet opening at one corner of the upper end of the radiator and an outlet opening at the foot, and across the front of the radiator, provides a complete enclosure for the radiator and in which a fan positioned in the inlet opening at the upper corner of the housing drives air around the surface areas of the radiator with the air escaping through the opening in the lower end of the front of the housing.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings, wherein:

Figure l is a front elevational view illustrating the improved radiator housing.

Figure 2 is an end elevational view of the radiator positioned around the lower part of 2,846,196 .Patented Aug.` 5, 1958 vthe opposite end of the radiator with the conventional radiator valve or vent shown in broken lines.

Figure 4 is a longitudinal section through the radiator housing taken on line 4--4 of Figure 2.

Figure 5 is a cross section through the radiator housing taken on line 5 5 of Figure 1.

Figure 6 is a typical cross section through the radiator housing showing the housing with the radiator removed and looking toward the end in which the opening for the radiator valve or vent is positioned.

Figure 7 is a sectional plan through the radiator housing taken from a point below the cover and showing `the fan or blower for circulating air through the housing.

Figure 8 is a view showing a sectional lplan similar to that shown in Figure 7 illustrating a modication wherein the side panels are provided'with filling elements that extend into openings between the sections of the radiator, thefan housing being shown in elevation.

Referring now to the drawings wherein like reference characters denote corresponding parts, the improved radiator housing of thisinvention includes a front wall 10, a rear wall 11, first and second end walls 12 and 13, a cover 14, and a fan 15 which is adapted to be actuated by a motor 16. I

The rlengthof the housing is such that the end wall 12 extends beyond the steam valve 17 and the opposite end `wall 13 `extends beyond the vent or radiator valve 18.

In order to hold the air` in close proximity to the surface area of the radiator 19 over which the housing is positioned, a partition 20 is spaced from the wall 12 and a vsimilar partition 21 is spaced inwardly from the end wall 13. Horizontally disposed supporting elements 22, 23 and 24 support the partition 20 from the end wall 12 and similar elements 25, 26 and 27 provide supporting means for a partition 21. The radiator or vent valve 18 is located-between the elements 25 and 26 .and the handle 2 8 of the steam valve 17 extends through an opening 29 in the member 24 whereby the handle 28 is positioned to register with an opening 30 in the end wall 12. The opening 30 is closed by a door 31 that is slidably mounted in rails 32 and that is provided with a handle 33. By'this means the door 31 is adapted to be moved upwardly to open the area 30 so that the handle 28 may be reached for opening and closing the valve.

The lower end of the end wall 12 extends downwardly to a oor surface, as indicated by the numeral 34, and the opposite end wall 13 and also the front wall 140 terminate at a point 35 providing a continuous escape opening 36 for air from the fan 15 along the front and one end of the radiator.

The housing is provided with supporting legs, as indicated by the numeral 37, which are positioned at the four corners, and which may also be positioned at other suitable points around the housing.

The fan 15 with the motor lindrical band or collar 38 positioned on a thin-gauge metal perforated plate 59 attached to the inside of the end wall 12 and, as shown in Figures 2 and 5, the plate 59 is provided with openings 39 through which air is drawn by the fan and, as indicated by the arrows 40, the air from the fan is circulated over the head of the radiator and downwardly Iaround the sections or coils thereof with the air coming in'close contact with the surface of the radiator and with the heated air being discharged through the openings 36.

The housing is provided with a toggle or button switch, as indicated by the numeral 41, which, as shown in Figure 4, is mounted on the perforated plate 59 'attached 16 are positioned in a cyyareas between the sections of the radiator.

vto the wall 12 andthe switch is connected by wires 42 to a suitable source of current-supply and to the motor 16. An oil cup 43 is also positioned on the plate 59 attached to the wall 12.

vor panels 47 and 48, which are preferably formed of insulating material and these panels retain air'being circulated through the radiator in relatively close contact with the surface area of the radiator.

In Figure 8 similar layers 49 and 50, of lining material, are placed against the inner surfaces of walls 51 'and 52 of a housing having end walls 53 and 54 Aand the panels `49 and 50 are provided with inwardly extended tongues 55 and 56 that'partially ll triangular-shaped -In this design the housing is provided with a fan S7 by which air is circulated through the housing, and the lower edge of `the front wall and end opposite to that in which the fan is positioned are spaced above the door providing outlet areas therein.

The partition 21, spaced from the end wall 13 of the housing is provided with an opening 58 which is positioned to receive the air valve -or vent 18 as the parts are assembled.

In order to obtain eiiciency in heating systems, particularly for residences, it is essential that air'be'circulated yover the hot areas of a radiator as quickly as possible `as with the air traveling continuously heat units, imparted thereto, are evenly distributed throughout a room vor other area in which the device is positioned.

It will be understood that other modifications, within =the scope of the Iappended claim, may be made in the design and arrangement of the parts without departing from the spirit of the invention.
